Motor slip speed calculator

Slip in this chapter is the difference between synchronous and actual rpm.

Sliprpm=Ns−Nactual\text{Slip}_{\text{rpm}} = N_{s} - N_{\text{actual}}

Worked example

Given

  • NactualN_{\text{actual}} = 1,765 rpm
  • NsN_{s} = 1,800 rpm
Sliprpm=1800−1765=35\text{Slip}_{\text{rpm}} = 1800 - 1765 = 35
